<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="driverClassName" value="${sqlserver.jdbc.driverClassName}" />
    <property name="url" value="${sqlserver.jdbc.url}" />
    <property name="username" value="${sqlserver.jdbc.username}" />
    <property name="password" value="${sqlserver.jdbc.password}" />
</bean>

由于该文件位于资源文件夹中，因此可以使用<context:property-placeholder location="classpath*:database.properties" />
